Summary

For ceramic whiteware industries that use slip casting as a forming method, plaster dominates as the mold material. As production cycles shorten to accommodate lower in-process inventories, and with more multiple casting or mechanized casting, more manufacturing plants require faster-casting slips. The role of the plaster mold becomes more important as process speeds increase. Plaster handling at the using plant, the water used to produce the molds, and the water/plaster ratio have increasingly important roles in casting performance.
